adds docs for resample, MODIS projection

[lazarusA]

Ok. I'm adding this because the usual just happened. I needed to do this, and yes, good luck finding docs or examples 😄 . Well, here, a version. It might need a second pass.

@asinghvi17 it would be also nice to include also your use cases.

resample does shiftlocus for you, it has to be Start for GDAL

I'll write a dropdown about what CRS is that we can include here, new users can then click on it if they need to.

Is this ready to merge?

[lazarusA]

there some things that might help, like saying or referencing to what crs is or a ProjString. Other that, I'm not planning on adding more.
